U.S. Rep. Patrick Murphy dodged raindrops to work the crowd at Barack Obama’s Sunday rally in Kissimmee.

Republican Marco Rubio has a sizable lead over Patrick Murphy in Florida’s U.S. Senate race, a new poll shows, with the Democrat unable to summon the strong support from women voters that are powering presidential candidate Hillary Clinton.

The presidential race in Florida remains a dead heat, according to the latest Quinnipiac University Poll. But the survey shows Rubio topping Murphy 50-43 percent in his bid for a second term in the U.S. Senate, which other polls show is likely to shift into Democratic hands following Tuesday’s elections.

Rubio is helped by overwhelming support from men, white voters and independents, who favor him 55-39 percent, Quinnipiac found. And while Murphy leads among non-white voters, women voters deadlocked at 46-46 percent, Quinnipiac found.

“U.S. Rep. Patrick Murphy is not getting the support a Democrat needs among women and non-white voters to overcome Sen. Marco Rubio’s lead among men and white voters,” Brown said.

Murphy, a two-term Congressman from Jupiter, has been outspent by Rubio, whose has a 3-to-1 advantage in money from outside groups supporting him. It’s translated into more TV ads and campaign organization.

Murphy introduced President Obama on Sunday at a big last-day-of-early-voting-rally in mostly Hispanic Kissimmee. But the Quinnipiac poll also shows that Rubio is holding a 48-46 percent edge on Murphy in early voting.

Quinnipiac polled 884 likely Florida voters from last Thursday through Sunday. The poll has a margin-of-error of plus-or-minus 3.3 percent.
